OPINION ALERT:
I think 802.11b is PLENTY fast enough for almost all residential uses. How often do you really need to move files around your own personal network at faster than a few M/s?
Over 99% of the network traffic on a home nework is routing out to or in from the cable or DSL modem, which I promise you is NOT running at any 802.11b speeds. THAT'S the bottleneck in the modern residential network. Anything faster than that out to the end-client is wasted bandwidth.
For home/noncommercial uses, .11a and especially .11g are overpriced, oversold overkill.
